摘要：

为了选出干旱区适宜金露梅嫩枝扦插繁殖育苗的扦插基质、生长调节剂及扦插日期，为大量繁殖金露梅苗木提供理论依据。于2008年6月5日至7月15日选择健壮、无病虫害当年生的半木质化嫩枝为试验材料，以扦插基质、植物生长调节剂、扦插时间等不同处理处理金露梅嫩枝进行金露梅嫩枝扦插试验，研究金露梅嫩枝扦插繁殖育苗的影响。结果表明：不同的处理组合均能显著或极显著的提高金露梅嫩枝扦插成活率，同时对苗期生长也有一定的影响。综合看来，育苗基质以土壤+蘑菇培养基废料的基质为最好，植物生长调节剂以500 mg/L IBA处理金露梅嫩枝扦插成活率最高，达85.45%，从其他综合性状看，各浓度的NAA处理金露梅嫩枝扦插，成活枝条的株高、平均生根数、平均根长显著高于其他组合的生长调节剂及对照；不同日期的嫩枝扦插成苗率都比较高，但以6月5日扦插最高，达88.85%。

Abstract:

In order to select suitable shoots arid Potentilla fruticosa cutting propagation of cutting seedling matrix and growth regulator and cutting date for many breed Potentilla fruticosa seedlings to provide theoretical basis. On June 5, 2008 to July 15 healthy, no choice in born of plant diseases and insect pests of half woodiness shoots as test materials, cutting matrix and plant growth regulator, cutting time waiting for different processed Potentilla fruticosa shoots Potentilla fruticosa shoots test was conducted Potentilla fruticosa shoots, studies the influence of cutting propagation of seedling. Results show that different treatment combinations were significantly or extremely significant improvement Potentilla fruticosa shoots survival rate, at the same time for cutting seedling stage growth also have certain effect. Comprehensive view, nursery substrates as soil + mushroom medium waste of matrix is the best, plant growth regulator to 500 mg/L IBA processing Potentilla fruticosa shoots cuttings, reaches the highest survival rate 85.45%, from other comprehensive characteristic look, the concentration of NAA would handle Potentilla fruticosa shoots cuttings, survival of branch height, average rooting number, average root length is significantly higher than other combinations of growth regulator and contrast, Different date with sprigs of cutting into sprout rate is higher, but in June 5, reaches the highest cutting 88.85%.
